Overall terrific trip along the Danube after three days in Prague. The AMA Sonata is new, sleek and comfortable; the crew were very polite, very efficient. Rooms were small but quite well planned and water pressure in showers always good. The tours were informative in positively beautiful sites, with equally beautiful cathedrals. Some tours were in very crowded popular spots e.g. Schonbrunn Palace. I preferred the less crowded ones. Tour guides ranged from good to excellent. Some highlights were: Vienna concert, local classic trio (La Strada) and on-board entertainer on keyboard, Tamas. Meals on boat were uniformly good but wine only so-so. Free time was barely adequate, but that may have been our fault for not taking more. We found great restaurants in Prague on our own, and other interesting events when we had the chance. Met very nice people on board. I took 400 plus photos.
